A while ago, I stopped starring Repositories on GitHub, instead I started to mirror them (given the license allows it) and/or simply used browser bookmarks. It's a lot more universal and mirroring makes sure, the stuff doesn't disappear.
If you wonder how I mirror all these repositories:
It's now more than 100 repositories and since I started to tag them consistently, they become my GitLab instance becomes a curated set of repositories.
@rugk For your first question, yes, gitlab has this functionality, but behind a paywall. (See the rational section)
And yes, I could add it to it, but then I would need to automatically push commits, and I'm usually quite reluctant to automate commits to a repository.
Technically yes, this would be possible.
This is my personal microblog. It's filled with my fun, joy and silliness.
